Speccation of Letters Patent.

Application filed May 26, 1910. Serial No. 563,504.

To all whom it may concern:

Be it known that I, DANIEL A. JONES, residing in Oshkosh, in the countyof Winnebago and State of WTisconsin, have invented new and usefulImprovements in Folding Anchors, of which the following is adescription, reference being had to the accompanying drawings, which area part of this specification.

This invention relates to improvements in anchors and particularly toanchors of the folding type which are adapted to be folded when not inuse in order to occupy but a minimum amount of space.

It is one of the objects of this invention to provide a folding anchorin which the stock and arms are adapted to fold into locked positionagainst the side of the shank.

A further object of this invention is to provide a folding anchor inwhich the stock and arms are operatively connected together so that whenthe stock members are folded downwardly against the shank the arms willbe caused to swing upwardly against the side of the shank and when infolded position the parts will be automatically locked in said position.

A further object of the invention is to provide al folding anchor inwhich the parts are automatically locked when swung into open positionand the parts cannot be swung to closed position until they are releasedfrom the locking means.

A further object of the invention is to provide a folding anchor whichis simple in construction and operation, easily assembled andinexpensive to manufacture.

lith the above, and other objects in view, the invention consists of theanchor and its parts and combinations as set forth in the claims, andall equivalents thereof.

In the accompanying drawing in which the same reference charactersindicate the same parts in all of the views: Figure 1 is a side view ofan anchor in open position, embodying the improvements, parts brokenaway to show interior construction; Fig. 2 is a side view thereof inclosed position; Fig. 3 is a view thereof taken at right angles to Fig.1, parts broken away to show interior construction; Fig. A is a detailfragmentary view of the upper portion of the anchor showing the stockmembers in folded position; Fig. 5 is a sectional detailed view of thestock members taken on line 5-5 of Fig. 3; and, Fig. 6 is a detail viewof the upper end of the connecting rod.

- Referring to the drawing the numeral 10 indicates the tubular shank ofthe anchor which is iormed of two like parts 11 and 12 riveted togetherand provided with enlargements 13 at the lower ends thereof which formthe throat 14 of the anchor. Arms 15 having iiattened points or flukesformed on their outer ends have their inner ends positioned between theenlargements and are pivotally connected thereto by pivot pins 16. Theinner ends of these arms are provided with segmental teeth 17 which meshwith rack teeth 18 formed on opposite sides of a connecting rod 19positioned within the tubular shank 10. The teeth on the arms and on theconnecting rod are suiicient in number to always int-ermesh in allpositions of adjustment of the arms. The segmental teeth of the arms 15are positioned eccentric to the axis of the arms so that when said armsare in their lowermost position the teeth will bind and lock and serveas stops to limit the further movement downwardly of the arms.

The upper portion 2O of the connecting rod is enlarged to form curvedshoulders 21 on opposite sides of the connecting rod and these shouldersextend upwardly at diagonally opposite corners to form stock memberengaging projections 22 which are adapted to engage the under edges ofthe angular portions 23 of stock members 24. The stock members, whichform the stock of the anchor, extend into the tubular portion of theshank through elongated openings 25 provided in opposite sides of saidshank and each member is pivotally connected to one of the walls of saidshank by a pivot pin 26. The connecting rod 19 is positioned between theinner ends of the stock members with the projecting shoulders 21 of therod engaging the lower edges of said members so that when the connectingrod is moved longitudinally with relation to the shank the stock memberswill be caused to swing on their pivotal connections. The upper portions27 of the shank forming the upper boundary edges of the elongatedopenings serve as stops to limit the swing 'of the stock members to openposition so that when in open position they will be substantially atright angles to the shank.

The upper end or head of the connecting rod extends through the upperend of the shank and has an eyed portion 28 to which is connected aring29 for the attachment of a rope thereto. A flat spring member BOconnected to the shank and provided with a locking pin 3l which extendsthrough an aperture 32 in the shank is adapted to lock the connectingrod to the shank when the parts are in open or closed position. Thelocking pin 8l is positioned to engage the recess provided in theconnecting' rod when the parts connected to said rod are in openposition, and when in folded position the pin engages the curvedshoulder 2l. A lip 3f-Ll extending from the side of the spring isprovided for convenience in releasing the lock.

In operation the anchor is unfolded or opened by swinging one of thearms downl wardly to open position. This movement will cause the upwardmovement of the connecting rod by means of the toothed engagement of thearm to the rod and will swing the other arm downwardly to position.Simultaneously with these movements the projections of the connectingrod will engage the lower edges of the stock members and swing themupwardly to open position. lVhen the rod has reached its uppermostposition the locking pin will spring into the recess and lock the partsin open position. The position of the teeth on the inner ends of thearms with relat-ion to the pivotalv connections of the arms and thelower teeth of the rod will serve to stop further movement of the armsdownwardly even though a strain is exerted against the tlukes and anypull of the rod upwardly will tend to bind the parts more securelytogether. ln closing or folding the anchor the spring is pressed torelease the .locking pin from the recess of the rod and either one ofthe arms or one of the stock members is swung against the shank, whichmovement will cause the other parts to fold simultaneously and thelocking pin passing over the curved shoulders of the r'od will be heldin locked position.

From the above description it will be seen that the anchor is verysimple in construction and operation and may be folded to occupy but aminimum amount of space.
